Allumiere is located on the highest peaks of the Tolfa Mountains, in the center of an area rich in history and of considerable archaeological and naturalistic interest. The fortunate geographical position of these mountains, the excellent conditions of habitability and the various economic resources have made their frequentation possible, since prehistoric times.

Allumiere, however, was bon as a town only in the early sixteenth century, following the discovery of alum which gave its name to the town. The discovery occurred in 1462 by Giovanni da Castro. But the real founder of the town was the Sienese banker Agostino Chigi, a leading figure in papal Rome, who during his term as contractor of the mines built the new factory, the aqueduct and the homes for the miners. Subsequently, the contract passed to the Olgiati family, who undertook an important urban planning campaign, aimed both at the construction of new homes for the miners and the construction of public buildings such as the Palazzo Camerale and the Camerale church, dedicated to S. Maria Assunta in Cielo, both commissioned by Pope Gregory XIII. In 1826, Pope Leo XII decreed the official birth of the new municipality of Allumiere, when mining activity had by then significantly reduced.

Today, only traces and memories remain of this mining activity.
